This invention relates to certain improvements in tobacco stemming andstripping machines, and particularly to that type of machine includingyieldable teeth, constituting the-stripping means for taking the leaffrom ,thestems.

The particular, object ofthis invention is the provision of equippingthe opposingfaces of thetoothed portion of the teeth with corrugations,which positively permits the leaves to be easily and quickly sev- 1 eredfrom the stems Without binding during such stripping action.

A further object of this invention is the provision of equipping theopposing faces of the toothed portion of the yieldable members with aseries of superposed corrugations, constituting a severing means wherebythe leaf may be easily and quickly severed from the stem during thestripping action.

A still further object of this invention is the provision of corrugatingthe toothed portions of the yieldable members so as to provide a meanswhereby the stripping action in separating the leaf from the stem. ma bepositively assured.

i still further object of this invention is the provision of a pluralityof teeth having one end provided with a forked portion, the opposingfaces of which forked portion is provided with corrugations,constitutlng a severing means for easily separating the leaf fromtobacco stems when placed therein or therethrough. 1

With these and other objects'in view, the invention consists in certainnovel features, combination and arrangement of parts as will behereinafter more fully described, i1- lustrated in the accompanyingdrawing, and claimed. 1

As this tooth is particularly adapted for as will be hereinafter 7 theabove entitledapplications, its mode of assembl is not described, as itis believed a that re erence to theparent applications is sufficientwithout further discussion, as to the particular construction ofassembly.

In the present invention, referring to the drawing in detail, thenumeral 5 indicates a body of a tooth, which in the impendingapplications is connected in series to form an endless unit ofindependently yieldable teeth.

a Each of the bodies 5 have one of their ends provided with a forkedportion 6, which forked portion has its opposing walls corrugated, as at7.

The corrugations 7 are arranged in-super posed relation on each wallandextend transversely through and beyond each side face or for theentire thickness of the body.

As clearly set forth,'the purpose of the corrugations is to provide ameanswhereby theistripping action, or the severing of the leaves fromthe stems'without binding will be assured, and thisis accomplished bythe corrugations, due to the fact thatthe corrugations will sever theleaves quickly and easily from the stems during the passage of thesteni1 through the forked portion of each toot 7 :used as str ppers andcarriers. e
